( GYROSCOPIC STEERING lvliic l'iAhtiFll 1 '0 all whom vYM/ia (Foo/war:

lie it known'that l, \Viimun l)ii-;'ri;i:. a citizen of the United States ot Ameriea. re-

siding in the horough ot' Brooklyn eounti'.

of Kings, eity and State of New York. have invented eertain new and useful Improvements in t \'i'oseopie Steering)lt rrlitiiiiflns. 'ot' whieh the following: is a speeitieation.

This invention relates to grroseopie steering meehanisms, sneh as are used lor St.(.ti' ing autoniohile torpedoes. In such in'e ha; iiisins, the gyroseope is spun up either h a spring motor or by the aetion ot' eonipressed air upon a turhiiie this spinnii'igrup oer-ur ring while the torpedo is still within the launching tube. or before it loses the direction or aim given it. he sueh tube. It. is desirahle to provide means for keeping the i1 roseope spinning at a sutlieiently high speed during its run, and for this purpose the use of compressed :ii' at it d ltttt tl hressure has been proposed.

Aceordingdo the. present invention. the, gyroseope ls spun up hy air at lii lrpri-ssure. being pi'et'erahl v the full initial pressure in the air tiaslgttnd is maintained spinning hy the turbine effect of ets ot air at redueed pressure taken from the exhaust of one or both the servo-motors ot' the torpedo, the intermittent exhaust hein e' stored up and equalized in a supplemental reservoir or hot.- t-le, so that a suhstai'itially steady How of air at diminished pressure is led to the gyroscope or fly wheel and raused to impinge thereon for. keeping it up to speed;-

The 'ireferahle embodiment of the invention is shown 'in, the aeiaimpanyin r draw ings wherein Figure 1 is a seliematie view. heine' in part.
